Gas tubes channel combustion gases from the barrel port to the bolt carrier group, cycling the action. This part addresses worn, damaged, or corroded factory tubes that can cause short-stroking or cycling failures. It's also essential when building a new pistol-length upper or swapping barrel configurations.\u003c\/p\u003e\u003cp\u003eManufactured from stainless steel with a salt bath nitride finish, this tube offers significantly improved corrosion and heat resistance compared to standard uncoated tubes. The nitriding process penetrates the metal surface rather than adding a coating that can flake or peel under sustained fire. Installation is straightforward for anyone familiar with AR-15 assembly—align the tube with the gas block and upper receiver, then secure with a roll pin. No gunsmithing or special tools required beyond a roll pin punch set.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Gas Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 (Pistol Length Gas System)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Salt Bath Nitride\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In (Roll Pin Punch Required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Gas Tube Only (Roll Pin Not Included)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"San Tan Tactical","offers":[{"title":"Default Title","offer_id":47939794043135,"sku":"STTGTP","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/1338399.jpg?v=1766546634","url":"https:\/\/doublestackstore.com\/products\/santan-ar15-gas-tube-ntrd-pstl-lngth","provider":"Double Stack Store","version":"1.0","type":"link"}
